Local governments require a plans review to ensure that proposed construction, renovations, and changes in occupancy comply with adopted building and fire codes before work begins. Reviewing plans allows officials to verify that fire protection systems, means of egress, fire-resistance features, and hazardous material controls are properly designed for the intended use of the building. A plans review also helps identify code deficiencies early, when corrections are less costly and easier to make, reducing delays, rework, and future enforcement issues.

Additionally, plans review promotes consistency in code enforcement, supports coordination between building and fire departments, and ensures public safety by minimizing fire and life safety risks before occupancy. By addressing potential hazards in advance, local governments protect lives, property, and emergency responders while ensuring buildings are safe, functional, and legally compliant.
